Figure 1.

Fiber‐hydrogel scaffold was successfully fabricated. A) Scaffold fabrication schematic diagram. B,C) SEM image of the entire scaffold and high magnification of PCL electrospun fibers (red box). A total of 50 fibers were quantified and the average fiber diameter was 1.35 ± 0.19 µm. Black arrow pointing out of the paper at the top right‐hand corner of (B) indicates the directionality of the fibers. D) Cumulative release of Neg miR and GDNF over time. All data are represented as mean ± SD.
